Definitions
- the present invention relates to a process for the biodegradation of a phenol plant aqueous efiluent stream.
- phenol plant is defined as a plant in which phenol is produced by the oxidation of cumene followed by decomposition of the oxidation product, cumene hydroperoxide, to phenol and acetone.
- Effluent streams from phenol plants normally contain water, traces of phenol and acetone and other impurities. Such eflluent streams give very low results when tested for biological oxygen demand (BOD) despite their high chemical oxygen demand (COD). It is believed that this is due to the presence of certain biocides, other than phenol itself which sten'lise the microorganism responsible for biodegradation in, for example, the standard BOD determination. It is very desirable that the effluent stream from a phenol plant should be biodegradable.
- a process for the biodegration of a phenol plant efiluent stream which process comprises treating the phenol plant eflluent stream with sulphur dioxide or a sulphur-containing compound prior to contacting the effluent with an activated sludge biodegration unit.
- Suitable sulphur-containing compounds include soluble metal sulphites, bisulphites and metal sulphides.
- the preferred compounds are sodium sulphite, sodium bisulphite and sodium sulphide.
- a convenient source of caustic sulphided liquor is the eifiuent stream from an ethylene cracking unit.
- a suitable source of sodium bisulphite liquor may be, for example, paper mill waste streams.
- the effiuent stream was contacted with activated sludge, slurried and allowed to settle.
- the example shows that treatment with sulphur dioxide greatly increased the test result for BOD, that is to say the biodegradability of the effluent stream.
- a process for the treatment of a phenol plant effluent stream to facilitate biodegradation thereof which comprises treating the phenol plant efiluent stream containing water, phenol, acetone and other impurities with sulphur dioxide, or a soluble metal sulphite, bisulphite, or sulphide.
- a process for the biodegradation of a phenol plant efiluent stream which comprises treating the phenol plant efliuent stream containing water, phenol, acetone and other impurities, with sulphur dioxide, or a soluble metal sulphite, bisulphite, or sulphide, and then contacting said efiiuent with an activated sludge biodegradation unit.
